UV spectrophotometer - UV semi transparent and semi reflective lens

Optical splitter, also known as half mirror, optical beam splitter, or beam splitter, is an optical component that can split light beams according to different wavelengths and intensity ratios.

This effect can be achieved through different optical designs such as semi transparent and semi reflective spectrometers. Half of the light can be reflected and half can be transmitted. The spectrometer only divides the light from the perspective of energy, optimizes it according to different wavelength ranges, and assigns the distribution ratio of light, such as 50% reflection: 50% transmission spectrometer, 30% reflection: 70% transmission spectrometer.

Inventory spectral ratios: 10 T 90 R, 20 T 80 R, 30 T 70 R, 40 T 60 R, 50 T 50 R, etc.

UV beam splitter is a type of optical glass substrate with a semi reflective semi transparent film coated on its surface and an anti reflective film coated on the other side. It can decompose ultraviolet light into two beams, one of which passes through and the other reflects.

UV spectrometers reflect a portion of the incident ultraviolet light energy, absorb a relatively small portion of the energy, and transmit the remaining ultraviolet light energy. Our company uses magnetron sputtering to produce them, and after the light passes through the filter, the penetration ratio can be changed, with half penetration and half reflection. They have low absorption characteristics and extremely smooth spectral curves, which are superior to most manufacturers in the market.
